Lecture Notes on Quantum Physics

Quantum physics is a catch-all term for the ideas, devices and technologies made possible by the development of quantum mechanics in the early part of the 20th century. This note concentrates on the ideas behind quantum mechanics itself, but the broader field of quantum physics encompasses everything from the science of electronic devices and lasers to the philosophical mysteries of quantum measurement theory.
